A 3D tour of Kīlauea's summit lava lake

This 3D model of the lava lake at Kīlauea's summit was constructed from a series of thermal images acquired during an overflight on Thursday, March 16. For scale, the lava lake is about 250 meters (820 ft) across. The lake is within the Overlook crater, which is within Halema‘uma‘u Crater. The model shows that a portion of the Overlook crater wall, along the southern wall of Halema‘uma‘u Crater, is overhanging. If this portion of the crater wall collapses it could trigger a small explosive event, similar to those which occurred in November and December of 2016.
